Lung Cancer: A Global Priority in Precision Oncology

Lung cancer is the leading cause of cancer-related death worldwide, with nearly 2.5 million new cases and 1.8 million deaths annually. Despite its enormous burden, lung cancer is increasingly treatable thanks to advances in early detection, genomic profiling, and personalized care. The World Health Organization (WHO) now recognizes lung cancer as a critical global health priority, calling for integrated strategies to improve outcomes and reduce disparities.

• Non-Small Cell Lung Cancer (NSCLC): The most common form, which includes adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. Molecular testing is essential for treatment planning.
• Small Cell Lung Cancer (SCLC): A fast-growing subtype often linked to tobacco use, typically diagnosed at advanced stages.
• Rare Subtypes: Includes lung cancers driven by uncommon genetic alterations, now identifiable through advanced diagnostics.

• Low-Dose CT Scans are the gold standard for screening high-risk individuals, significantly improving survival.
• Liquid Biopsies and Comprehensive Genomic Profiling (CGP) enable non-invasive, precision-based diagnosis.
• AI-enhanced imaging is being adopted to improve early detection and staging accuracy.
•  WHO urges countries to implement national screening strategies with equitable access and follow-up care.

Lung cancer treatment is increasingly biologically tailored and stage-specific. Options include:

• Surgery, especially for early-stage NSCLC
• Radiation Therapy, including stereotactic techniques for localized tumors
• Chemotherapy, often used in combination with other modalities
• Targeted Therapies, based on molecular drivers
• Immunotherapy, now standard in many treatment pathways
• Clinical Trials, offering access to innovative therapies

The WHO’s 2025 resolution on lung health calls for:

• Integrated national policies that include lung cancer in primary care systems
• Evidence-based guidelines for early detection and diagnosis
• Affordable access to quality diagnostics and technologies
• Public awareness campaigns to reduce stigma and elevate lung cancer as a policy priority3

Primary prevention remains essential. WHO emphasizes:

• Tobacco control as the most effective strategy
• Air pollution reduction
• Occupational safety regulations
• Smoke-free environments and education initiatives
